Question

what are the equation of a line parallel to x axis and y axis​

Answer 1

Answer:

Hence, the equation of a straight line parallel to x-axis at a distance b from it is y = b.

The equation of x-axis is y = 0, since, x-axis is a parallel to itself at a distance 0 from it.

Or

Let P (x,y) be any point on the x-axis. Then clearly, for all position of P we shall the same ordinate 0 or, y = 0.

Therefore, the equation of x-axis is y = 0.

If a straight line is parallel and below to x-axis at a distance b, then its equation is y = -b.
